摘要:

Sparganosis is an infection caused by migrating larvae of the cestode genusSpirometra. There have been ∼62 cases of sparganosis reported in the United States. Although a subcutaneous mass is the most common manifestation, sparganosis is not well-described in the dermatology literature. We present a case of cutaneous sparganosis in a 52-year-old Filipino American woman. Histologically, the sections showed a granulomatous panniculitis and dermatitis containing a section of a sparganum. A transverse section of an intact sparganum reveals an eosinophilic cuticle, loose stroma, calcareous bodies, and smooth muscle fibers.

摘要:

The authors describe a benign adenomatous neoplasm arising from anogenital mammary-like glands. These glands have been recently recognized in the anogenital region and may play an important role in the development of some neoplastic disorders peculiar to this anatomical area. Important features of the tumor are adenomatous tubular and cystic structures with apocrine-like cytologic features, a lobular configuration, and abundant fibrous stroma.

摘要:

Malignant transformation within an adnexal neoplasm with features of spiradenoma and cylindroma is reported in a 60-year-old woman. The malignant component of the tumor consisted of areas of solid carcinoma, with focal squamous metaplasia. In the benign component, apart from the features of spiradenoma and cylindroma, sebaceous differentiation was present adjacent to a cystic space lined by apocrine epithelium. The morphologic composition of this unusual neoplasm supports the concept of a histogenetic relationship between cylindromas and spiradenomas, including their differentiation toward the pilosebaceous-apocrine unit.

摘要:

Malignant chondroid syringoma, also called malignant mixed tumor of the skin, is a rare variant of a malignant tumor derived from sweat gland cells. Histologically the tumor is composed of an epithelial and a mesenchymal component. The epithelial structures show glandular differentiation and carcinomatous features. They are embedded in a mucinous stroma with spindle mesenchymal cells and areas of chondroid differentiation. The epithelial cells express cytokeratins. The luminal epithelial cells show binding to the lectinUlex europaeus;intraluminal cells are carcinoembryonic antigen positive. The stromal cells are cytokeratin negative and sporadically positive for vimentin. Chondroid areas are S-100 protein and vimentin positive. No labeling for actin is seen.

摘要:

Hair follicle nevushas been variously defined as a specific type of neoplasm with follicular differentiation or as a synonym for trichofolliculoma; the latter view has predominated in recent years. We report a nodular lesion that was identified histopathologically as a hamartoma with follicular differentiation and that systematic serial sectioning showed not to be a trichofolliculoma. After reviewing previous descriptions of lesions diagnosed as hair follicle nevus, and in the light of our own observations, we believe that hair follicle nevus is a distinct type of adnexal hamartoma.

摘要:

A 55-year-old woman had a history of prolonged vaginal bleeding. Dilatation and curettage confirmed poorly differentiated endometrial adenocarcinoma. After hysterectomy, salpingo-oophorectomy, and 5,040 cGy of postoperative irradiation, lung metastases developed, which temporarily responded to chemotherapy that included adriamycin and cisplatin. Metastatic lesions developed later in the left acetabulum and the hallux. The latter, clinically reminiscent of pyogenic granuloma, affected only skin. The poorly differentiated toe metastasis duplicated areas of the primary endometrial adenocarcinoma and was immunohistochemically similar to it. While appearing quite rarely, and generally late in the disease, pedal skin lesions may represent metastases from known or occult visceral cancers.
